PolyStar

PolyStar Sport has been an internationally registered trademark since
1981. It was PolyStar's founder Horst Schulze who teamed up with
researchers at the former Hoechst AG to perfect the idea of the
monofilament synthetic string. Under the name PolyStar, the string
soon established itself as a pioneering development on the
international tennis-string market, inspiring professionals and
amateurs alike. The company stands for quality as well as continual investment in
research and development. Moreover, the playing characteristics of their tennis strings have been put to the test by internationally
renowned players.
